Definitions
- the present invention relates to a compact cell with a protective housing for welding processes using welding robots, in which a work area to be enclosed can be modularly adapted by moving a protective cover.
- Robot cells for welding processes of this type known from the prior art usually comprise one or more work spaces, implemented by a worktop or other holders that fix a workpiece, a movable welding robot and an outer shell that encloses the welding robot and the work surface, which protects the welder during the welding processes of the welding robot and directs the resulting welding fumes into a designated extraction device.
- the protective shell is usually provided with a door, a window or at least curtains, so that the welder can quickly reach the respective work area in the event of a workpiece exchange or due to manual settings on the welding robot.
- Such a device is described in document WO2019/138033A1 disclosed.
- the compact cell with a protective housing for welding processes and/or cutting processes using welding robots can comprise a protective housing consisting of at least a cell roof and a cell side wall, which can be connected to a cell base frame by a guide device and can thus be moved bidirectionally from a first to a second position to enclose at least a first or second work area integrated in the compact cell.
- the guide device can preferably be controlled pneumatically, but in further preferred embodiments also motor-, electrically and/or pneumatically supported.
- the protective housing can have a roller door device at least on the front and rear, which can move roller doors up and down in a modular manner to enclose the respective work area located in the protective housing and thus offers preferred access to the respective work area.
- Moving the protective housing from one position to the next can also free up at least one work area for a welder, whereas another work area can be completely closed by the protective housing and thus used as a work surface for the welding robot installed in the compact cell.
- This design provides a cost-effective and at the same time flexible design of a robot welding cell.
- the method of the protective housing and the resulting modular, changeable work areas enable the welder to work in an optimized, safe manner in parallel while the robot is welding, while at the same time a maximum work area ratio can be provided.
- this arrangement offers a high level of compactness and Transportability so that it can be easily integrated into existing systems and loaded from at least 3 of 4 sides and from above.
- the protective housing comprises four side walls, each of which has at least one roller shutter device.
- the above-mentioned cell side wall can therefore be formed by a roller shutter device in this development, so that easy access is possible from all sides.
- the protective housing is designed as a portal on (preferably four) columns, whereby a roller shutter device and/or a welding curtain can be provided between each of these columns.
- a welding curtain can also be provided on at least one and preferably on all sides of the protective housing.
- the first working area can preferably be a front working area directed towards the front of the protective housing and the second working area can be a rear working area directed towards the rear of the protective housing.
- the cell side wall is preferably made in one piece, consists of an iron or aluminum alloy or of a heat-resistant polymer and can preferably include areas for attaching welding curtains.
- the side wall preferably includes at least one viewing window, which in a particularly preferred development can also consist of heat-resistant and UV-filtering material and allows a view of the enclosed work area. The working welder can thus be efficiently protected from possible damage (flying sparks, UV radiation, etc.) during robot welding, while at the same time being able to easily observe the welding process and/or cutting process through the window.
- the viewing window can also be provided in a roller shutter preferably attached to the cell side wall.
- the side wall can also be firmly connected to the cell roof, preferably by a weld seam or screw connections, and thus forms the movable framework of the protective housing.
- the types of construction mentioned have the advantage of ensuring a compact, lightweight and stable form of the protective housing. Consequently, a robust and at the same time cost-effective body can be provided to protect the welder.
- the cell roof can also preferably be made of heat-resistant material, preferably metal or plastic, and can preferably contain a housing for the integration of additional elements.
- At least one suction opening can preferably be provided on the cell roof, so that when the protective enclosure is moved, a suction device provided on the suction opening, preferably integrated into the roof, can be carried along. This means that the extraction of harmful welding fumes from different work areas can be achieved by a single suction device and thus implemented effectively.
- the suction device can be connected to the compact cell (or the suction opening) in other positions, for example externally (in the factory hall) and with a movable hose.
- the suction device can also be integrated on the underside of the cell, for example in a welding table used as a work surface or on the side wall of the cell.
- a downward-guided suction device such as a movable hose or a movable pipe system can preferably be used to suction the enclosed work space.
- the latter embodiment has the additional advantage that only the desired areas are suctioned using a movable guide system, which can further minimize the necessary suction power and thus the energy costs incurred.
- At least one front roller shutter device can also be found on the front side and one rear roller shutter device on the back side of the protective enclosure, which at least one preferably made of metal Provide a roller door on a roller door suspension preferably integrated in the roof housing and guide the roller door from the roof surface to the work surface for closing and from the work surface to the roof surface for opening.
- the roller doors can preferably also comprise an integrated roller grille and/or windows or window areas (which are made, for example, from welding protection glass) for observing the work area inside the protective housing.
- roller doors When the roller doors are closed or opened, they are flush with the aforementioned side walls or with the sides of the protective housing, so that when both roller door devices are closed, a space is created on all sides for the work area located under the protective housing and the open position of at least one roller door device allows access to the work area enclosed by the protective housing.
- This structure therefore not only enables efficient enclosure of the respective work area, but also simplified accessibility of the latter by partially opening and closing the roller doors.
- At least one of the roller shutter devices can be integrated on three sides (particularly preferably on all four sides) of the above-mentioned protective housing, with preferably at least one roller shutter on each of the roller shutter devices being able to completely close the respective side of the protective housing. This enables the complete enclosure of the respective work area located under the protective housing, with the additional roller shutter device realizing improved modularity of the work areas and optimized accessibility.
- the individual roller doors of the roller door devices can preferably be opened and closed independently by a drive module and preferably comprise a safety device to prevent objects or body parts from becoming trapped.
- individual roller doors can also be connected in a modular manner in order to divide a work area into different sub-work areas by opening and closing individual roller door combinations. This device enables a The respective work area can be enlarged or modulated particularly effectively and quickly, whereby the work process used can be made even more efficient.
- at least one roller door can also be provided on the front and rear roller door device, which can completely close the respective (front or rear) side of the protective housing for faster modulation of these partial work areas.
- the roller shutter devices also comprise at least one drive for opening and closing the roller shutter device and preferably at least one safety device for preventing trapping incidents. Due to the precise, electrical control of the roller shutters, these additional elements allow the movement of the latter to be defined even more precisely and their safety standard to be optimized in every respect for use in a parallel welding process.
- roller shutter devices can be opened and closed independently of one another, which allows for even greater modularity of the structure.
- At least one guide rail can be attached to the lower side of the roof and this can rest on a fixed, motionless guide device.
- the guide device can preferably be controlled pneumatically or (only) with pneumatic support, so that possible wear and tear caused by moving the protective housing and the risk of injury during the process are minimized due to integrated sensors.
- the control of the guide device can also be carried out electrically or mechanically, which can lead to a more precise or easier to implement movement mechanism for the protective housing.
- the guide device is also attached to at least one static base frame, so that the The protective housing can be moved on the guide device along the base frame at least from a first position to enclose the first work area to a second position to enclose the second work area and back.
- the base frame is preferably fastened within the side wall of the protective housing during the movement of the protective housing from one position to another and back, so that the important guide elements are particularly efficiently protected during the movement, but also when transporting the entire compact cell.
- the compact cell can, for example, also comprise at least a first, a second and a third work area in succession along a longitudinal axis, with the protective housing continuing to enclose the individual work areas by linear movement along the longitudinal axis defined by the base frame and thus continuing to provide optimal protection for the welder even in more complex structures.
- the guide device is further preferably configured in such a way that alternating welding operations are possible, ie the protective housing in the second position can completely enclose the second work area, whereby, for example, the first work area is made freely accessible to the welder and when the protective housing is moved to the first position, the front work area can be enclosed, whereas the rear work area(s) is/are released.
- the walls and roller doors of the The protective housing is flush with the frame of the work area in at least one position, thus providing advantageous transportability and compactness of the compact cell.
- the guide device can preferably be configured such that after moving the protective housing from at least one position to the other position, at least one working area is no longer enclosed by the protective housing on all sides.
- the base frame is further connected to at least one modular welding table, preferably on both sides of the table, whereby the base frame not only gains further stability, but the work areas used can also be further optimized.
- the welding table is also preferably provided with a perforated grid plate so that the welding table can be used as a support for at least one of the work areas for the precise adjustment of work materials and other elements.
- each work area also comprises at least one modular welding table or welding plate, whereby a welding table can comprise further elements, such as an additional welding device for the welder, drawers or a connection point to another work area, which can significantly facilitate the general welding process within the compact cell and accelerate the production speed.
- the modular welding table can preferably be configured in relation to the base frame in such a way that it is enclosed on all sides in at least one position of the protective housing, which not only allows optimal compactness and transportability of the compact cell to be achieved, but also improves protection for the welder.
- a modular welding table also offers the possibility of further optimizing the above-mentioned preferred division of the work surfaces.
- the hole grid in a particularly preferred display type can at least a further modular partition wall aligned along the direction of the protective enclosure can be integrated into one of the work areas and combined with at least one of the modular roller doors of the rear or front roller door devices.
- work areas can be divided into smaller sub-work areas when the respective roller door devices are closed, which can also be enclosed on all sides.
- the partition wall can preferably also be implemented using a roller door, so that the respective work areas can be put together modularly by opening and closing the respective roller doors.
- the welding robot to be used can preferably also be positioned on the welding table, on the side walls of the protective housing or on the inside of the cell roof on a support or a rail connected to the above-mentioned elements in at least one of the work areas.
- a welding robot can be selected that is provided with a manipulator at at least one station and can be moved in at least one axis of rotation, which can preferably also be a cobot.
- Such a robot therefore makes it possible to carry out even complex welding work, whereby the hole grid incorporated in the welding table can make the positioning or fixing of the latter even more flexible and thus allow the welding system further degrees of freedom.
- the cobot preferably weighs less than 40 kilograms, which means that, unlike a classic industrial robot system, it can be used flexibly wherever it is needed. While the robot is welding, the employee can withdraw and does not have to breathe in the welding fumes.
- the cobot is also very easy to program. With manual guidance and operation via touch panel, teaching new tasks is possible after a short training period. With a free-drive function, the cobot or the burner can be moved very easily by hand to the place where it should start and end. Intermediate waypoints can also be set. and sections are programmed in this way.
- the cobot (or collaborative robot) delivers consistently high quality welds that require little to no rework.
- cobots are technically designed so that they can work safely in direct proximity to people without a protective fence.
- the cobot ensures the required safety in direct contact with the operator through a unique 6-fold force and torque monitoring system, which enables flexible interaction between the robot and its environment.
- An advantageous cobot preferably fulfills the collaboration type according to the technical specification ISO TS15066.
- the cobot can be taught the position points very quickly by moving them by hand without any programming knowledge and at the same time workpieces can be positioned in the optimal welding position using the additional axes and thus processed productively on multiple sides.
- the cobot carries out a precise movement of the torch, the welding system delivers the perfect seam.
- the collaborative robot preferably has a learning mode to learn a working movement of the welding torch to process the workpiece and a working mode to carry out the working movement learned in the learning mode, whereby the working mode enables both welding and cutting of the workpiece.
- the positioning of the welding robot on the side walls of the protective housing or the cell roof enables the welding robot to move along with the protective housing to enclose a respective work area and to be used to process the workpiece located in the work area.
- Such an embodiment therefore not only offers optimal compactness or space utilization of the compact cell, since such an attachment allows more work surface to be realized on the associated welding table, but also prevents any restrictions that may arise during the process. the protective enclosure around or through a fixed welding robot position.
- the guide device of the protective housing is configured at least in relation to the position of the welding robot in such a way that the welding robot can be enclosed from every side by the protective housing in the first position and preferably also by the protective housing in the other positions and automatically closes all sides before each welding process.
- Such a construction makes it possible to ensure optimal safety for the welder without impairing the movement of the protective housing.
- the welding robot can preferably also be positioned on a robot guidance system, i.e. a rail or an eccentric swivel or concentric rotary axis on the welding table or again on the side wall of the protective housing or on the cell roof.
- a robot guidance system i.e. a rail or an eccentric swivel or concentric rotary axis on the welding table or again on the side wall of the protective housing or on the cell roof.
- the welding robot can thus independently move between the above-mentioned, modularly defined partial work areas or switch between the respective work areas via an external control system, and thus manage even complex, spatially distributed work steps.
- the process steps can thus be further optimized by choosing the robot guidance system and additional work area can be created thanks to the minimal area requirement (e.g. of the rotary axis).
- the above-mentioned features make it possible to create a compact welding cell which, in particular thanks to the movable protective housing and the resulting alternating welding operation, not only allows for optimized process steps with maximum use of the work area, but also provides the best possible protection for the welder at any time during the process.

- the protective housing is also mounted on a pneumatically actuated guide on a base frame so that it can be moved between a first position for enclosing a first work area and at least a second position for enclosing a second work area.
- a pneumatically actuated guide on a base frame so that it can be moved between a first position for enclosing a first work area and at least a second position for enclosing a second work area.
- the guide can preferably be designed so that the welding robot positioned in at least one of the work areas and controllable by several degrees of freedom can be enclosed from all sides in at least one position, which not only ensures the best possible protection but also the largest possible work area for the robot.
- Other features, such as the modular welding table also provide the ability to adapt to the individual welding process required, which can be further maximized by dividing the work areas into sub-work areas using a combination of modular roller shutter devices and partition walls.
- the compact cell can preferably be a mobile compact cell, which includes at least one forklift pocket for transport, so that in one of the two positions of the protective housing in particular, the compact cell can be transported through the forklift pocket with a pallet truck, thus making transport of the compact cell even easier.

- the support 16 of the welding robot 15 is attached to the table top 14 in such a way that the smallest distance exists between the welding robot 15 and the partition wall 19, while the welding robot can still reach the entire space of the partial work area AB2 enclosed by the partition wall 19 and the left roller door 18.
- the embodiment shown can also be constructed in such a way that the welding robot 15 can move between the two partial work areas AB1, AB2, with the partition wall 19 remaining in place throughout all welding processes to protect the welder on the side of the partial work area not currently being used by the welding robot 15.
- an extremely compact alternating welding process can be implemented that can only be used on one side, in which the welder and the welding robot 15 can constantly switch between the first AB1 and the second partial work area AB2.
- Such a procedure is advantageous, for example, if at the same time another welding job is being prepared in the second work area A2 and thus the protective housing3 cannot be moved from the first to the second position.
- FIG 5B shows the individual modification of the welding operation using the same welding robot 15, introduced into the Figure 4B illustrated embodiment. Since the welding robot 15 can weld independently in the second work area A2 and workpieces 11, 13, 17 can be exchanged independently of one another by different welders by opening and closing the modular roller doors 18, 20, a 2-man alternating welding system can also be implemented without problems using such a device, in particular using the partition wall 19 installed in the front work area A1.
- the rolling door devices 22A, 22B for opening and closing the modular rolling doors 18, 20 located at the front 4A and the rolling door 5B located at the rear 4B of the protective enclosure 3 are also shown in the Figures 4A , B and 5A, B.
- the respective roller doors 18, 20, 5B are initially fastened to a roller door suspension V1, V2, V3 integrated in the roof 1 or in the hollow structures 29A, 29B of the roof 1, so that they can be stored as protected as possible during the process of the protective housing 3 or the general welding process.
- a motor (not shown in the figure) with a control unit linked to the roller door devices 22A, 22B controls the opening and closing of the roller doors 18, 20, 5B.
- Figure 6A the guide structure used to move the protective enclosure 3 is shown, which is equally in Figure 6B shown in an enlarged manner.
- two linear guide rails 23 are attached along the front axis of the protective housing 3 to the underside of the roof 1 or to the underside of the above-mentioned hollow structure frame, wherein the length of the guide rails 23 defines the travel length of the associated protective housing 3.
- the same guide rails 23 are also each seated on two pneumatically controllable guide devices 24, which move the protective housing 3 in the respective direction via the guide rail 23 in order to move the protective housing 3 from the first to the second position and back.
- the respective guide devices are also firmly connected to a base frame 25 and via a further connection of the base frame 25 to the respective side wall of the welding table 8, as well as on both sides to the latter welding table 8.
- the movement of the protective housing 3 can be optimally stabilized, whereby the compactness of the compact cell Z is maintained by the base frame 25 which lies closely against the welding table 8.
- Figure 6C which the embodiment of the Figures 1 to 3 the compact cell Z in three-dimensional view and without protective housing 3, the structure of the base frame 25 is also shown in more detail.
- the base frame 25 is firmly connected on both sides to the respective outer sides of the welding table 8 and forms beam structures at the rear ends of the welding table 8, which rest on the rear corners of the welding table 8 for additional stabilization and define the height of the respective protective housing 3. Accordingly, the pneumatic guide devices 24 for moving the protective housing 3 are attached to the upper ends of the beam structure, so that when the guide rail 23 of the protective housing 3 is placed on top, the movement of the latter further benefits from the stability of the base frame 25.
- the Figure 7 shows a further embodiment of the compact cell Z in plan view, with the protective housing 3 shown in the first position and with the already shown Figure 4A or 5A.
- the welding robot 15 is in this case adjusted on a linear guide rail 26 parallel to the longitudinal axis of the welding table 8, so that it can move more easily between the two partial work areas AB1, AB2 of the first work area A1 and can reach the individual areas of the partial work areas AB1, AB2 or workpieces 13, 17 more easily.
- the support 30 of the welding robot 15 connected to the guide rail 26 is rotatably mounted, whereby an equally simplified approach to the second work area A2 or the workpiece 11 stored there can be realized in the event of a change in position of the protective housing 3.
- a control unit (not shown) connected to the motor of the guide rail 26 also enables a programmable work sequence of the welding robot 15.
- FIG. 8A and 8B another embodiment of the welding robot support 27 is shown within a side view of the already shown Figure 1-3 illustrated embodiment of the protective housing 3, wherein the protective housing 3 in Figure 8A in the first and in Figure 8B remains in the second position.
- the welding robot 15 is mounted on an eccentrically mounted and on the welding table plate 14, so that the welding robot 15 can also be moved in the direction of the front or rear 4A, 4B of the protective housing 3 as an additional degree of freedom and can thus be brought closer to the respective workpiece 11, 13 even more precisely and easily.
- the work surface to be used can be used even more effectively with the help of an eccentric rotation axis 27, which further optimizes the embodiment shown compared to those previously shown.
- FIGS 9A and 9B also show the Figures 8A and 8B illustrated embodiment of the welding robot support 27 in the embodiment of the protective housing 3 provided with modular roller doors 18, 20, as already shown in the Figures 4A , B and 5A , B illustrated, where Figure 9A the corresponding protective housing 3 in the first position and Figure 9B shows the same in the second position.
- the high modulability of the work area division by the individually positioned roller doors 18, 20, 5B is combined with the precise control of the welding robot 15 to the workpieces 11 by the eccentrically mounted support rotation axis 27.
- none of the embodiments shown impairs the protective housing 3 process in the direction of the first or second position, which equally shows the high modulability of the invention shown.
- FIGS 10 and 11 describe a further embodiment of the compact cell Z, in which within the already specified Figures 1 and 2
- the welding robot 15 can be positioned above the welding table by means of a connecting device 30 fixedly attached to the cell roof 1.
- the Figure 10 shows a front view of the above-mentioned embodiment, whereby in particular by positioning the welding robot 15 above the workpiece 13 to be processed, an improved accessibility of the latter compared to the welding robot 15 is ensured and thus the precision of the coincident welding work can be further optimized.
- this embodiment has the advantage that the welding robot 15, by being attached to the movable protective housing 3, can be moved along with the protective housing 3, whereby not only can any restrictions on the movement of the protective housing around the position of a fixed welding robot 15 be avoided, but the welding robot 3 can also be brought even closer to the respective workpiece 11, 13, 17 with the help of a control unit attached to the protective housing 3.
- Figure 11 also shows the Figure 10 described embodiment in a three-dimensional representation, starting from the bottom of the compact cell Z.
- the position of the connecting device 30, to which the welding robot 15 is connected to the cell roof 1, is once again shown in more detail.
- the welding robot 15 by attaching the welding robot 15 to the protective housing 3, more work surface can be created on the welding table 8, whereby the work-to-cell area ratio of the compact cell Z can be optimized once again.
- FIGS 12 A - C describe a further embodiment of the welding robot positioning, in which the welding robot 15 is additionally connected via a connecting device 30 to a linear guide rail 31 attached to the roof of the protective housing 3 and with which Fig.4 and 5 shown embodiment of the protective housing 3 together with the welding table 8.
- FIG 12A The front view of this compact cell Z is shown, whereby the welding robot 15 can be moved between the two partial work areas AB1, AB2 via the linear guide rail 31 aligned parallel to the front roller door, thus optimally reaching the workpieces 13, 17 separated from each other by the partition wall 19.
- the positioning of the welding robot 15 on the cell roof 1 of the protective housing 3 also results in the advantages that the work surfaces of the partial work areas AB1, AB2 on the welding table 8 are not additionally occupied by the Welding robot 15 or the associated guide rail 31 can be made smaller and the welding robot 15 can be brought even more precisely to the respective workpiece by moving along during the movement of the protective housing 3.
- FIGS 12B and 12C describe a lateral cross-section of the already in Figure 12A embodiment of the compact cell Z, where Figure 12B the protective housing 3 in the second position and Figure 12C shows the same device with the protective housing in the first position.
- the movement of the protective housing3 in this embodiment is defined by the geometry of the base frame 25 or the size of the guide rail 23 and thus has no further restrictions (e.g. a maximum travel length due to elements fixed on the welding table 8).
- This embodiment therefore also allows larger or even geometrically freely modelable compact cells Z to be realized.
- FIGS 13A - C represent a further embodiment of the compact cell Z, in which the design of the protective housing 3 mentioned on page 23, line 8ff, together with the welding robot 15 attached to the cell roof 1, has been combined with a welding table consisting of three work areas A1, A2, A3.
- the Figure 13A shows the embodiment of the compact cell Z in side view with the protective housing 3 in the second position, ie enclosing the second work area A2.
- the work areas A1, A2, A3 are not defined by two or more welding plates, but are arranged one behind the other and overlapping one another on a single welding table 8.
- the first work area A1 again describes the front side 4A (see e.g. Fig. 12C ) of the protective housing 3 the front working area A1 of the compact cell Z and the second A2 or third working area A3 respectively the middle or rear working area of the invention.
- the above-mentioned base frame 25 or the guide device 24 is configured in this case such that the protective housing 3 can be moved successively from a first position for enclosing the first work area A1, via a second position for enclosing the second work area A2 to at least a third position for enclosing the third work area A3 and back, so that by moving the protective housing 3, at least every area of the welding table 8 located under the protective housing 3 can be enclosed once and areas that are not enclosed are left free.
- This has the advantage that any number of work areas can be made available and thus not only one or two welding workers can prepare or process workpieces 11, 13, 17 in parallel to the welding robot, but the compact cell Z can be assembled as desired depending on the requirements of the respective welding job.
- the movement of the protective housing 3 can also be defined more precisely by a control unit, so that the positions of the protective housing 3 can be redefined at any time before the respective welding work.
- Figure 13B also describes the protective housing 3 of this embodiment in more detail.
- the respective roller doors 5A, 5B, 5C can also include protective curtains 32A, 32C, so that when the roller doors 5A, 5B, 5C are lowered, the protection of the welders is ensured, but at the same time a view of the interior of the protective housing 3 is made possible.
- these protective curtains (or roller door grille structures) 32A, 32B can preferably close automatically when the welding robot 15 located inside the protective housing 3 is carrying out welding work, so that sparks or possible welding fumes can be completely prevented.
- FIG 13C a three-dimensional visualization of the same embodiment is also shown, with the roller doors 5A, 5C of the protective housing 3 still being closed.
- the compact cell in this embodiment can be operated from every side and the associated protective housing 3 is closed by at least one roller door 5A, 5C on three of the four sides of the protective housing 3
- This device therefore offers optimized accessibility, especially in the case of parallel welding work using welding robots 15.
- FIGS 13D - F describe a further embodiment of the compact cell Z with three working areas A1, A2, A3, wherein in this case a holder with manipulator 32 aligned along the longitudinal axis of the welding table plate 14 and positioned on the first and second working areas was additionally attached.
- FIG. 13D This embodiment is shown in a three-dimensional view with the protective housing 3 in the third position, ie over the third working area A3.
- the manipulator 32 in this case has a rotation axis intended for clamping a workpiece 33, here aligned along the long side of the welding table plate 14, which supports the workpiece 33 so that it can rotate and thus makes it accessible from all sides for the welding robot 15 during welding.
- the shapes and degrees of freedom of the manipulator 32 are not limited to the Figures 13D - F shown illustration.
- the manipulator 32 can preferably also move the workpiece 33 in a translational manner relative to its original position or rotate it in more than one axis and thus ensure optimal processing of the latter by the welding robot 15.
- several manipulators 32 can also be implemented, preferably also on several welding table plates 14.
- the side walls 4C, 4D of the protective housing 3 are provided with lightweight welding curtains for optimised movement of the protective housing 3 and to protect the manipulator 32 from possible contact damage, so that especially when moving the protective housing 3 from a working area A3 without the manipulator 32 (see Fig. 13D ) to a working area A1, A2 provided with a manipulator 32, as shown in Figure 13E shown, it is not possible to damage the workpiece 33 inserted in the manipulator 32 even when the side walls 4C, 4D are lowered.
- the shape of the manipulator 32 or the workpiece 33, openings or opening hatches may be provided on the side walls 4C, 4D, whereby the enclosure of the manipulator or the workpiece 33 32 or parts of the latter can be carried out entirely without contact with the protective housing 3.
- the protective housing shown comprises four sides, with a welding curtain being provided on two sides and a roller shutter device on the other two sides.
- the cell side wall can therefore be formed by a roller shutter device or welding curtain in this development, so that easy access is possible from all sides of the protective housing.
- the protective housing is designed as a movable/slidable portal on four columns, with a roller shutter device and/or a welding curtain preferably being provided between these columns.
- the Figures 14A and 14B also describe the already mentioned Figures 13 A - C illustrated embodiment of the compact cell Z, in which in this case the three roller doors 5A, 5C of the protective housing were opened and the protective housing 3 was moved to the third position or over the third work area A3. Due to the positioning of the welding robot 15 by means of the connecting device 31 on the cell roof 1, the workpiece 11 can be optimally processed again, while the additional movement of the welding robot 15 through the protective housing 3 means that the welding robot 15 can be positioned in a different work area A1, A2 after completion of the work.
- This process can preferably be automated, e.g. by the above-mentioned control unit (not shown), so that an optimized work chain can be made possible.
- This embodiment of the compact cell Z thus realizes optimal accessibility of the individual work areas in combination with the possibility of expanding and automating parallel welding work as desired.

Gattungsgemäße aus dem Stand der Technik bekannte Roboterzellen für Schweißvorgänge umfassen zumeist ein oder mehrere Arbeitsräume, realisiert durch eine Arbeitsplatte oder sonstige, ein Werkstück fixierende Aufnahmen, einen bewegbaren Schweißroboter sowie eine den Schweißroboter und die Arbeitsfläche umschließende Außenhülle, die den Schweißer während den Schweißvorgängen des Schweißroboters schützt und den entstehenden Schweißrauch in eine vorgesehene Absaugvorrichtung lenkt. Die Schutzhülle ist dabei meist mit einer Tür, einem Fenster oder zumindest Vorhängen versehen, sodass der Schweißer im Falle eines Werkstückaustausches oder aufgrund manueller Einstellungen am Schweißroboter schnell an den jeweiligen Arbeitsbereich gelangt. Eine solche Vorrichtung ist in Dokument
In der
Es ist eine Aufgabe der vorliegenden Erfindung eine gattungsgemäße Schweißroboterzelle so auszubilden, dass diese eine möglichst kompakte Form mit einer möglichst optimalen Zugänglichkeit der jeweiligen Arbeitsbereiche aufweist. Zudem ist es eine Aufgabe die Struktur der Schweißroboterzelle so zu optimieren, dass die vorgelegten Arbeitsräume möglichst optimal genutzt werden können ohne den Schutz des Schweißers zu vernachlässigen.It is an object of the present invention to design a welding robot cell of this type in such a way that it has the most compact form possible with the best possible accessibility of the respective work areas. In addition, it is an object to optimize the structure of the welding robot cell in such a way that the work spaces provided can be used as optimally as possible without neglecting the protection of the welder.
Zur Lösung der vorstehend genannten Aufgabe werden die Merkmale der unabhängigen Ansprüche vorgeschlagen. Die abhängigen Ansprüche betreffen bevorzugte Ausführungsbeispiele der vorliegenden Erfindung.To achieve the above-mentioned object, the features of the independent claims are proposed. The dependent claims relate to preferred embodiments of the present invention.
Die Kompaktzelle mit einer Schutzumhausung für Schweißvorgänge und/oder Schneidvorgänge mittels Schweißroboter kann eine zumindest aus einem Zellendach und einer Zellenseitenwand bestehenden Schutzumhausung umfassen, welche durch eine Führungsvorrichtung mit einem Zellengrundrahmen verbunden sein kann und so zur Umschließung eines in der Kompaktzelle integrierten zumindest ersten oder zweiten Arbeitsbereichs bidirektional jeweils von einer ersten in eine zweite Position gefahren werden kann. Dabei kann die Führungsvorrichtung vorzugsweise pneumatisch, in weiteren bevorzugten Ausführungsformen jedoch auch motorisch, elektrisch und/oder auch pneumatisch unterstützt ansteuerbar sein. Darüber hinaus kann die Schutzumhausung zumindest an der Vorder- und Rückseite eine Rolltorvorrichtung aufweisen, welche Rolltore zur Umschließung des jeweiligen, in der Schutzumhausung liegenden Arbeitsbereiches modular auf- und abwärts bewegen kann und so einen bevorzugten Zugang zum jeweiligen Arbeitsbereich bietet. Das Verfahren der Schutzumhausung von einer Position in die nächste kann ferner zumindest jeweils einen Arbeitsbereich für einen Schweißer freigeben, wohingegen ein anderer Arbeitsbereich durch die Schutzumhausung komplett geschlossen und so als Arbeitsfläche des in der Kompaktzelle eingebauten Schweißroboters genutzt werden kann. Durch diese Ausgestaltung wird eine kostengünstige und zugleich flexible Ausgestaltung einer Roboterschweißzelle bereitgestellt. Insbesondere ermöglicht das Verfahren der Schutzumhausung und die so entstehenden, modular wechselbaren Arbeitsbereiche ein optimiertes, sicheres paralleles Arbeiten des Schweißers während der Schweißarbeiten des Roboters, wobei zugleich ein maximales Arbeitsflächenverhältnis zur Verfügung gestellt werden kann. Zudem bietet diese Anordnung durch ihre vorteilhafte Konstruktion eine hohe Kompaktheit und Transportierbarkeit, sodass sie sich problemlos in bereits bestehende Systeme integrieren und von mindestens 3 von 4 Seiten und oben beladen lässt.The compact cell with a protective housing for welding processes and/or cutting processes using welding robots can comprise a protective housing consisting of at least a cell roof and a cell side wall, which can be connected to a cell base frame by a guide device and can thus be moved bidirectionally from a first to a second position to enclose at least a first or second work area integrated in the compact cell. The guide device can preferably be controlled pneumatically, but in further preferred embodiments also motor-, electrically and/or pneumatically supported. In addition, the protective housing can have a roller door device at least on the front and rear, which can move roller doors up and down in a modular manner to enclose the respective work area located in the protective housing and thus offers preferred access to the respective work area. Moving the protective housing from one position to the next can also free up at least one work area for a welder, whereas another work area can be completely closed by the protective housing and thus used as a work surface for the welding robot installed in the compact cell. This design provides a cost-effective and at the same time flexible design of a robot welding cell. In particular, the method of the protective housing and the resulting modular, changeable work areas enable the welder to work in an optimized, safe manner in parallel while the robot is welding, while at the same time a maximum work area ratio can be provided. In addition, this arrangement offers a high level of compactness and Transportability so that it can be easily integrated into existing systems and loaded from at least 3 of 4 sides and from above.
In einer bevorzugten Weiterbildung umfasst die Schutzumhausung vier Seitenwände welche jeweils zumindest eine Rolltorvorrichtung aufweisen. Die o.g. Zellenseitenwand kann daher bei dieser Weiterbildung von einer Rolltorvorrichtung gebildet werden, sodass eine einfache Zugänglichkeit von allen Seiten möglich ist. Die Schutzumhausung ist bei dieser Weiterbildung als Portal auf (bevorzugt vier) Säulen ausgebildet wobei zwischen diesen Säulen jeweils eine Rolltorvorrichtung und/oder ein Schweißvorhang vorgesehen sein kann. Besonders bevorzugt kann zudem ein Schweißvorhang an zumindest einer und bevorzugt an allen Seiten der Schutzumhausung vorgesehen sein.In a preferred development, the protective housing comprises four side walls, each of which has at least one roller shutter device. The above-mentioned cell side wall can therefore be formed by a roller shutter device in this development, so that easy access is possible from all sides. In this development, the protective housing is designed as a portal on (preferably four) columns, whereby a roller shutter device and/or a welding curtain can be provided between each of these columns. Particularly preferably, a welding curtain can also be provided on at least one and preferably on all sides of the protective housing.
In einem bevorzugten Ausführungsbeispiel kann dabei der erste Arbeitsbereich bevorzugt ein zur Vorderseite der Schutzumhausung gerichteter, vorderer Arbeitsbereich sein und der zweite Arbeitsbereich ein, auf die Hinterseite der Schutzumhausung bezogener, hinterer Arbeitsbereich.In a preferred embodiment, the first working area can preferably be a front working area directed towards the front of the protective housing and the second working area can be a rear working area directed towards the rear of the protective housing.
Ferner ist die Zellenseitenwand vorzugsweise in einem Stück gefertigt, besteht aus einer Eisen oder Aluminiumlegierung oder aus einem hitzebeständigen Polymer und kann bevorzugt Bereiche zur Anbringung von Schweißervorhängen umfassen. Darüber hinaus umfasst die Seitenwand vorzugsweise zumindest ein Sichtfenster, welches in einer besonders bevorzugten Weiterentwicklung ebenso aus hitzebeständigem und UV-filterndem Material bestehen kann und den Blick auf den umschlossenen Arbeitsbereich ermöglicht. Somit kann der arbeitende Schweißer effizient von eventuellen Schädigungen (Funkenflug, UV-Strahlung etc.) während des Roboterschweißbetriebes geschützt werden, während er gleichzeitig den Schweißvorgang und/oder Schneidvorgang leicht über das Fenster beobachten kann. In einer besonders bevorzugten Ausführungsform kann das Sichtfenster auch in einem bevorzugt an der Zellenseitenwand angebrachten Rolltor vorgesehen sein.Furthermore, the cell side wall is preferably made in one piece, consists of an iron or aluminum alloy or of a heat-resistant polymer and can preferably include areas for attaching welding curtains. In addition, the side wall preferably includes at least one viewing window, which in a particularly preferred development can also consist of heat-resistant and UV-filtering material and allows a view of the enclosed work area. The working welder can thus be efficiently protected from possible damage (flying sparks, UV radiation, etc.) during robot welding, while at the same time being able to easily observe the welding process and/or cutting process through the window. In a particularly preferred embodiment, the viewing window can also be provided in a roller shutter preferably attached to the cell side wall.
Bevorzugt kann die Seitenwand zudem fest mit dem Zellendach, vorzugsweise durch eine Schweißnaht oder Verschraubungen, verbunden werden und bildet so das verfahrbare Gerüst der Schutzumhausung aus. Die genannten Konstruktionsarten besitzen dabei den Vorteil eine kompakte, gewichtstechnisch leichte und stabile Form der Schutzumhausung zu gewährleisten. Folglich lässt sich ein robuster und zugleich kostengünstiger Körper zum Schutz des Schweißers bereitstellen. Das Zellendach kann ebenso bevorzugt aus hitzebeständigem Material, vorzugsweise Metall oder Kunststoff, gefertigt sein und kann vorzugsweise ein Gehäuse zur Integration von Zusatzelementen beinhalten.Preferably, the side wall can also be firmly connected to the cell roof, preferably by a weld seam or screw connections, and thus forms the movable framework of the protective housing. The types of construction mentioned have the advantage of ensuring a compact, lightweight and stable form of the protective housing. Consequently, a robust and at the same time cost-effective body can be provided to protect the welder. The cell roof can also preferably be made of heat-resistant material, preferably metal or plastic, and can preferably contain a housing for the integration of additional elements.
Darüber hinaus kann bevorzugt zumindest eine Ansaugöffnung am Zellendach realisiert sein, sodass beim Verfahren der Schutzumhausung eine an der Ansaugöffnung vorgesehene, bevorzugt auf dem Dach integrierte Ansaugvorrichtung mitgeführt werden kann. Hierdurch kann das Absaugen des schädlichen Schweißrauches an verschiedenen Arbeitsbereichen durch eine einzelne Ansaugvorrichtung realisiert und somit effektiv umgesetzt werden.In addition, at least one suction opening can preferably be provided on the cell roof, so that when the protective enclosure is moved, a suction device provided on the suction opening, preferably integrated into the roof, can be carried along. This means that the extraction of harmful welding fumes from different work areas can be achieved by a single suction device and thus implemented effectively.
In einer weiteren, bevorzugten Ausführungsform, kann die Absaugvorrichtung in anderen Positionen, wie zum Beispiel extern (in der Werkshalle) und mit einem bewegbaren Schlauch mit der Kompaktzelle (bzw. der Ansaugöffnung) verbunden werden. Gleichermaßen kann die Ansaugvorrichtung auch an der Unterseite der Zelle, etwa in einem als Arbeitsfläche genutzten Schweißtisch oder an der Zellenseitenwand, integriert sein. Zudem kann bevorzugt eine nach unten geführte Absaugung wie beispielsweise ein bewegbarer Schlauch oder ein verfahrbahres Röhrensystem, zum Absaugen des umschlossenen Arbeitsraums genutzt werden. Letztere Ausführungsform besitzt dabei den zusätzlichen Vorteil, dass durch ein bewegliches Führungssystem auch nur gewünschte Flächen abgesaugt werden was die notwendige Ansaugstärke und somit die entfallenden Energiekosten weiter minimieren kann.In a further preferred embodiment, the suction device can be connected to the compact cell (or the suction opening) in other positions, for example externally (in the factory hall) and with a movable hose. The suction device can also be integrated on the underside of the cell, for example in a welding table used as a work surface or on the side wall of the cell. In addition, a downward-guided suction device such as a movable hose or a movable pipe system can preferably be used to suction the enclosed work space. The latter embodiment has the additional advantage that only the desired areas are suctioned using a movable guide system, which can further minimize the necessary suction power and thus the energy costs incurred.
Vorzugsweise lassen sich zudem zumindest eine vordere Rolltorvorrichtung an der Vorderseite und eine hintere Rolltorvorrichtung an der Rückseite der Schutzumhausung wiederfinden, welche zumindest ein vorzugsweise aus Metall bestehendes Rolltor an einer bevorzugt im Dachgehäuse integrierten Rolltoraufhängung bereitstellen und das Rolltor zum Schließen von der Dachfläche zur Arbeitsfläche und zum Öffnen von der Arbeitsfläche zur Dachfläche führen. Weiterhin können die Rolltore vorzugsweise auch ein integriertes Rollgitter und/oder Fenster oder Fensterbereiche (welche beispielsweise aus Schweißerschutzglas hergestellt sind) zur Beobachtungdes in der Schutzumhausung inneren Arbeitsbereiches umfassen. Beim Schlie-ßen bzw. Öffnen der Rolltore schließen diese bündig mit den vorgenannten Seitenwänden bzw. mit den Seiten der Schutzumhausung ab, sodass sich in einer geschlossenen Stellung beider Rolltorvorrichtungen ein zu allen Seiten umschlossener Raum für den unter der Schutzumhausung befindlichen Arbeitsbereich ergibt und die geöffnete Stellung zumindest einer Rolltorvorrichtung den Zugriff auf den von der Schutzumhausung umschlossenen Arbeitsbereich ermöglicht. Somit lässt sich mit diesem Aufbau nicht nur eine effiziente Umschließung des jeweiligen Arbeitsbereiches ermöglichen, sondern ebenso eine vereinfachte Zugänglichkeit letzteren durch eine teilweisen Öffnung und Schließen der Rolltore realisieren.Preferably, at least one front roller shutter device can also be found on the front side and one rear roller shutter device on the back side of the protective enclosure, which at least one preferably made of metal Provide a roller door on a roller door suspension preferably integrated in the roof housing and guide the roller door from the roof surface to the work surface for closing and from the work surface to the roof surface for opening. Furthermore, the roller doors can preferably also comprise an integrated roller grille and/or windows or window areas (which are made, for example, from welding protection glass) for observing the work area inside the protective housing. When the roller doors are closed or opened, they are flush with the aforementioned side walls or with the sides of the protective housing, so that when both roller door devices are closed, a space is created on all sides for the work area located under the protective housing and the open position of at least one roller door device allows access to the work area enclosed by the protective housing. This structure therefore not only enables efficient enclosure of the respective work area, but also simplified accessibility of the latter by partially opening and closing the roller doors.
In einer besonders bevorzugten Ausführungsform kann an der oben genannten Schutzumhausung auch an drei Seiten (besonders bevorzugt an allen vier Seiten) zumindest eine der Rolltorvorrichtungen integriert sein, wobei vorzugsweise zumindest ein Rolltor an jeder der Rolltorvorrichtungen in der Lage sein kann die jeweilige Seite der Schutzumhausung komplett zu verschließen. Hierdurch wird die komplette Umschließung des jeweiligen, unter der Schutzumhausung liegenden Arbeitsbereiches ermöglicht, wobei die zusätzliche Rolltorvorrichtung eine verbesserte Modularität der Arbeitsbereiche sowie eine optimierte Zugänglichkeit realisiert.In a particularly preferred embodiment, at least one of the roller shutter devices can be integrated on three sides (particularly preferably on all four sides) of the above-mentioned protective housing, with preferably at least one roller shutter on each of the roller shutter devices being able to completely close the respective side of the protective housing. This enables the complete enclosure of the respective work area located under the protective housing, with the additional roller shutter device realizing improved modularity of the work areas and optimized accessibility.
Darüber hinaus können die einzelnen Rolltore der Rolltorvorrichtungen vorzugweise jeweils unabhängig durch ein Antriebsmodul geöffnet und geschlossen werden und umfassen bevorzugt eine Sicherungseinrichtung, um mögliches Einklemmen von Gegenständen oder Körperteilen zu vermeiden. In einer besonders bevorzugten Form können einzelne Rolltore zudem modular verbunden werden, um so, durch Öffnen und Schließen einzelner Rolltorkombinationen, einen Arbeitsbereich in verschiedene Teilarbeitsbereiche aufzuteilen. Durch diese Vorrichtung lässt sich ein jeweiliger Arbeitsbereich besonders effektiv und schnell vergrößern bzw. modulieren, wodurch der genutzte Arbeitsablauf noch effizienter gestaltet werden kann. Bevorzugt kann zudem zumindest ein Rolltor an der vorderen und der hinteren Rolltorvorrichtung bereitgestellt sein, das zur schnelleren Modulation dieser Teilarbeitsbereiche die jeweilige (Vorder- oder Rück-)Seite der Schutzumhausung komplett verschließen kann.In addition, the individual roller doors of the roller door devices can preferably be opened and closed independently by a drive module and preferably comprise a safety device to prevent objects or body parts from becoming trapped. In a particularly preferred form, individual roller doors can also be connected in a modular manner in order to divide a work area into different sub-work areas by opening and closing individual roller door combinations. This device enables a The respective work area can be enlarged or modulated particularly effectively and quickly, whereby the work process used can be made even more efficient. Preferably, at least one roller door can also be provided on the front and rear roller door device, which can completely close the respective (front or rear) side of the protective housing for faster modulation of these partial work areas.
Bevorzugt umfassen die Rolltorvorrichtungen zudem zumindest einen Antrieb zum Öffnen und Schließen der Rolltorvorrichtung und bevorzugt zumindest eine Sicherungseinrichtung zur Vermeidung von Einklemmvorfällen. Durch diese Zusatzelemente lässt sich aufgrund der genauen, elektrischen Ansteuerung der Rolltore die Bewegung letzterer noch präziser definieren sowie deren Sicherheitsstandart für den Gebrauch in einem parallelen Schweißverfahren in allen Maßen optimieren.Preferably, the roller shutter devices also comprise at least one drive for opening and closing the roller shutter device and preferably at least one safety device for preventing trapping incidents. Due to the precise, electrical control of the roller shutters, these additional elements allow the movement of the latter to be defined even more precisely and their safety standard to be optimized in every respect for use in a parallel welding process.
Darüber hinaus können die Rolltorvorrichtungen unabhängig voneinander geöffnet und geschlossen werden, wodurch eine nochmals verbesserte Modularität des Aufbaus realisiert werden kann.In addition, the roller shutter devices can be opened and closed independently of one another, which allows for even greater modularity of the structure.
Zum Verfahren der Schutzumhausung von zumindest einer in eine andere Position und zurück, kann in einem bevorzugten Aufbau zumindest eine Führungsschiene an die untere Seite des Daches angebracht sein und diese auf einer festen, bewegungsfreien Führungsvorrichtung aufliegen. Dabei ist die Führungsvorrichtung vorzugsweise pneumatisch oder (nur) pneumatisch unterstützt ansteuerbar, sodass mögliche Abnutzungen durch das Verfahren der Schutzumhausung sowie das Verletzungsrisiko während des Verfahrens aufgrund von integrierter Sensorik minimiert wird. Alternativ kann die Steuerung der Führungsvorrichtung zudem elektrisch oder mechanisch vollzogen werden, was jeweils zu einem genaueren oder vereinfach zu realisierenden Verfahrmechanismus der Schutzumhausung führen kann.In order to move the protective housing from at least one position to another and back, in a preferred design at least one guide rail can be attached to the lower side of the roof and this can rest on a fixed, motionless guide device. The guide device can preferably be controlled pneumatically or (only) with pneumatic support, so that possible wear and tear caused by moving the protective housing and the risk of injury during the process are minimized due to integrated sensors. Alternatively, the control of the guide device can also be carried out electrically or mechanically, which can lead to a more precise or easier to implement movement mechanism for the protective housing.
In einer besonders bevorzugten Vorrichtungsdarstellung ist die Führungsvorrichtung zudem zumindest an einen statischen Grundrahmen befestigt, sodass die Schutzumhausung auf der Führungsvorrichtung entlang des Grundrahmens zumindest von einer ersten Position zur Umschließung des ersten Arbeitsbereiches in eine zweite zur Umschließung des zweiten Arbeitsbereiches und zurück verfahrbar ist. Eine solche Ausführung ermöglicht es die Form der Kompaktzelle möglichst optimal zu gestalten, da die Geometrie und Größe der zu schützenden Arbeitsbereiche somit lediglich von der Form des Grundrahmens abhängt. Darüber hinaus ist der Grundrahmen vorzugsweise während des Verfahrens der Schutzumhausung von einer Position in eine andere und zurück innerhalb der Seitenwand der Schutzumhausung befestigt, sodass die wichtigen Führungselemente einen besonders effizienten Schutz während des Verfahrens, jedoch auch beim Transport der gesamten Kompaktzelle erfahren.In a particularly preferred device representation, the guide device is also attached to at least one static base frame, so that the The protective housing can be moved on the guide device along the base frame at least from a first position to enclose the first work area to a second position to enclose the second work area and back. Such a design makes it possible to design the shape of the compact cell as optimally as possible, since the geometry and size of the work areas to be protected thus only depend on the shape of the base frame. In addition, the base frame is preferably fastened within the side wall of the protective housing during the movement of the protective housing from one position to another and back, so that the important guide elements are particularly efficiently protected during the movement, but also when transporting the entire compact cell.
Insbesondere ermöglicht ein solcher Grundrahmen auch bei mehr als zwei Arbeitsbereichen eine optimale Verfahrbarkeit der Schutzumhausung. So kann in einer bevorzugten Ausführungsform der Erfindung, die Kompaktzelle beispielsweise auch zumindest einen ersten, einen zweiten und einen dritten Arbeitsbereich aufeinanderfolgend entlang einer Längsachse umfassen, wobei die Schutzumhausung weiterhin durch lineares Verfahren entlang der durch den Grundrahmen definierten Längsachse die einzelnen Arbeitsbereiche jeweils umschließen und somit den Schweißer selbst in komplexeren Aufbauten weiterhin optimal schützen kann.In particular, such a base frame enables optimal mobility of the protective housing even when there are more than two work areas. In a preferred embodiment of the invention, the compact cell can, for example, also comprise at least a first, a second and a third work area in succession along a longitudinal axis, with the protective housing continuing to enclose the individual work areas by linear movement along the longitudinal axis defined by the base frame and thus continuing to provide optimal protection for the welder even in more complex structures.
Die Führungsvorrichtung ist weiterhin bevorzugt so konfiguriert, dass ein wechselseitiger Schweißbetrieb ermöglicht wird, d.h. die Schutzumhausung in der zweiten Position den zweiten Arbeitsbereich vollkommen umschließen kann, wobei beispielsweise der erste Arbeitsbereich für den Schweißer frei zugänglich gemacht wird und beim Verfahren der Schutzumhausung in die erste Position der vordere Arbeitsbereich umschließbar wird, wohingegen der oder die hinteren Arbeitsbereiche freigegeben wird/werden. Somit kann eine permanente Parallelarbeit des Schweißers zur Vorbereitung des nächsten Arbeitsschrittes oder Schweißstücks ermöglicht werden, was gleichermaßen die Effektivität des Schweißvorgangs weiter erhöht. Zudem können in einem besonders bevorzugten Aufbau die Wände und Rolltore der Schutzumhausung in zumindest einer Position bündig mit Rahmen des Arbeitsbereiches abschließt, sodass eine vorteilhafte Transportierbarkeit und Kompaktheit der Kompaktzelle entsteht.The guide device is further preferably configured in such a way that alternating welding operations are possible, ie the protective housing in the second position can completely enclose the second work area, whereby, for example, the first work area is made freely accessible to the welder and when the protective housing is moved to the first position, the front work area can be enclosed, whereas the rear work area(s) is/are released. This enables the welder to work permanently in parallel to prepare for the next work step or weld piece, which also further increases the effectiveness of the welding process. In addition, in a particularly preferred construction, the walls and roller doors of the The protective housing is flush with the frame of the work area in at least one position, thus providing advantageous transportability and compactness of the compact cell.
Somit kann die Führungsvorrichtung bevorzugt so konfiguriert sein, dass nach dem Bewegen der Schutzumhausung von zumindest einer Position in die andere Position, zumindest ein Arbeitsbereich nicht mehr von der Schutzumhausung von allen Seiten umschlossen wird.Thus, the guide device can preferably be configured such that after moving the protective housing from at least one position to the other position, at least one working area is no longer enclosed by the protective housing on all sides.
Vorzugsweise ist der Grundrahmen ferner mit zumindest einem modularen Schweißtisch verbunden, bevorzugt an beiden Seiten des Tisches, wodurch der Grundrahmen nicht nur an weiterer Stabilität gewinnt, sondern die genutzten Arbeitsbereiche ebenso weiter optimiert werden können. Aus diesem Grund ist auch der Schweißtisch bevorzugt mit einem Lochrasterplatte versehen, sodass der Schweißtisch als Auflage für zumindest eine der Arbeitsbereiche zur genauen Justierung von Arbeitsmaterialien und anderen Elementen genutzt werden kann. In einer besonders bevorzugten Ausführungsform umfasst jeder Arbeitsbereich darüber hinaus zumindest einen modularen Schweißtisch oder eine Schweißplatte, wobei ein Schweißtisch weitere Elemente, wie etwa ein zusätzliches Schweißgerät für den Schweißer, Schubladen oder eine Verbindungsstelle zu einem anderen Arbeitsbereich umfassen kann, was den allgemeinen Schweißvorgang innerhalb der Kompaktzelle erheblich erleichtern und die Produktionsgeschwindigkeit beschleunigen kann.Preferably, the base frame is further connected to at least one modular welding table, preferably on both sides of the table, whereby the base frame not only gains further stability, but the work areas used can also be further optimized. For this reason, the welding table is also preferably provided with a perforated grid plate so that the welding table can be used as a support for at least one of the work areas for the precise adjustment of work materials and other elements. In a particularly preferred embodiment, each work area also comprises at least one modular welding table or welding plate, whereby a welding table can comprise further elements, such as an additional welding device for the welder, drawers or a connection point to another work area, which can significantly facilitate the general welding process within the compact cell and accelerate the production speed.
Zudem kann der modulare Schweißtisch im Bezug zum Grundrahmen bevorzugt so konfiguriert sein, dass er in zumindest einer Position der Schutzumhausung von allen Seiten umschlossen ist, wodurch sich nicht nur eine optimale Kompaktheit bzw. Transportierbarkeit der Kompaktzelle realisieren lässt, sondern ebenso ein verbesserter Schutz des Schweißers erreicht wird.In addition, the modular welding table can preferably be configured in relation to the base frame in such a way that it is enclosed on all sides in at least one position of the protective housing, which not only allows optimal compactness and transportability of the compact cell to be achieved, but also improves protection for the welder.
Zusätzlich bietet ein modularer Schweißtisch auch die Möglichkeit die obengenannte, bevorzugte Einteilung der Arbeitsflächen weiter zu optimieren. So kann durch das Lochraster in einer besonders bevorzugten Darstellungsart zumindest eine weitere, modulare und längs der Schutzumhausungs-Verfahrensrichtung gerichtete Trennwand in eine der Arbeitsbereiche integriert und mit zumindest einem der modularen Rolltoren der hinteren oder vorderen Rolltorvorrichtungen kombiniert werden. Durch eine solche Vorrichtung lassen sich somit in der geschlossenen Stellung der jeweiligen Rolltorvorrichtungen Arbeitsbereiche in kleinere Teilarbeitsbereiche einteilen, welche ebenso zu allen Seiten umschlossen werden können. Bevorzugt kann die Trennwand dabei auch durch ein Rolltor realisiert werden, sodass sich die jeweiligen Arbeitsbereiche durch Öffnen und Schließen der jeweiligen Rolltore modular zusammensetzen lassen können.In addition, a modular welding table also offers the possibility of further optimizing the above-mentioned preferred division of the work surfaces. For example, the hole grid in a particularly preferred display type can at least a further modular partition wall aligned along the direction of the protective enclosure can be integrated into one of the work areas and combined with at least one of the modular roller doors of the rear or front roller door devices. With such a device, work areas can be divided into smaller sub-work areas when the respective roller door devices are closed, which can also be enclosed on all sides. The partition wall can preferably also be implemented using a roller door, so that the respective work areas can be put together modularly by opening and closing the respective roller doors.
Der zu nutzende Schweißroboter kann bevorzugt ebenso auf dem Schweißtisch, an den Seitenwänden der Schutzumhausung oder der Innenseite des Zellendaches auf einer Auflage oder einer mit den oben genannten Elementen verbundenen Schiene in zumindest eine der Arbeitsbereiche positioniert sein. Dabei kann in einer besonders bevorzugten Ausführungsform ein durch einen Manipulator an zumindest einer Station versehener, zumindest in einer Drehachse bewegbarer Schweißroboter gewählt werden, der bevorzugt auch ein Cobot sein kann. Durch einen solchen Roboter ist es folglich möglich selbst komplexe Schweißerarbeiten zu erfüllen, wobei die in dem Schweißtisch eingearbeiteten Lochraster die Positionierung bzw. Fixierung letzteren noch flexibler gestalten können und somit dem Schweißsystem weitere Freiheitsgrade ermöglichen.The welding robot to be used can preferably also be positioned on the welding table, on the side walls of the protective housing or on the inside of the cell roof on a support or a rail connected to the above-mentioned elements in at least one of the work areas. In a particularly preferred embodiment, a welding robot can be selected that is provided with a manipulator at at least one station and can be moved in at least one axis of rotation, which can preferably also be a cobot. Such a robot therefore makes it possible to carry out even complex welding work, whereby the hole grid incorporated in the welding table can make the positioning or fixing of the latter even more flexible and thus allow the welding system further degrees of freedom.
Der Cobot wiegt bevorzugt weniger als 40 Kilogramm, wodurch er im Gegensatz zu einer klassischen Industrieroboteranlage flexibel dort eingesetzt werden kann, wo er gerade benötigt wird. Während der Roboter schweißt, kann sich der Mitarbeiter zurückziehen und muss so den Schweißrauch nicht einatmen. Der Cobot ist zudem sehr leicht zu programmieren. Mit Handführung und einer Bedienung per Touch-Panel ist das Teachen neuer Aufgaben schon nach kurzer Einarbeitung möglich. Mit einer Free-Drive-Funktion kann der Cobot bzw. der Brenner ganz simpel per Hand an die Stelle bewegt werden, an der er starten und enden soll. Auch Zwischenwegepunkte und Abschnitte werden so programmiert. Der Cobot (oder kollaborative Roboter) liefert eine gleichbleibend hohe Qualität der Schweißnähte, die wenig bis gar keine Nacharbeit erfordert.The cobot preferably weighs less than 40 kilograms, which means that, unlike a classic industrial robot system, it can be used flexibly wherever it is needed. While the robot is welding, the employee can withdraw and does not have to breathe in the welding fumes. The cobot is also very easy to program. With manual guidance and operation via touch panel, teaching new tasks is possible after a short training period. With a free-drive function, the cobot or the burner can be moved very easily by hand to the place where it should start and end. Intermediate waypoints can also be set. and sections are programmed in this way. The cobot (or collaborative robot) delivers consistently high quality welds that require little to no rework.
Zudem sind Cobots technisch so ausgelegt, dass sie ohne Schutzzaun in direkter Nachbarschaft zu Menschen sicher arbeiten können. Die geforderte Sicherheit im direkten Kontakt mit dem Bediener gewährleistet der Cobot durch eine einzigartige 6-fache Kraft- und Momentenüberwachung, die eine flexible Interaktion zwischen dem Roboter und seiner Umgebung ermöglicht. Ein vorteilhafter Cobot erfüllt bevorzugt die Kollaborationsart gemäß der technischen Spezifikation ISO TS15066.In addition, cobots are technically designed so that they can work safely in direct proximity to people without a protective fence. The cobot ensures the required safety in direct contact with the operator through a unique 6-fold force and torque monitoring system, which enables flexible interaction between the robot and its environment. An advantageous cobot preferably fulfills the collaboration type according to the technical specification ISO TS15066.
Wird die Kompaktzelle oder Cobot-Schweißzelle mit Zusatzachsen (Positioniervorrichtung) ausgestattet, kann dem Cobot ohne Programmierkenntnisse mittels verschieben von Hand sehr schnell die Positionspunkte gelernt werden und gleichzeitig Werkstücke mittels den Zusatzachsen in optimale Schweißlage positioniert werden und somit produktiv auch mehrseitig bearbeitet werden. Der Cobot führt eine präzise Bewegung des Brenners aus, das Schweißsystem liefert die perfekte Naht. Bevorzugt weist der kollaborative Roboter einen Lernmodus auf um eine Arbeitsbewegung des Schweißbrenners zum Bearbeiten des Werkstücks zu erlernen und einen Arbeitsmodus um die im Lernmodus erlernte Arbeitsbewegung durchzuführen, wobei der Arbeitsmodus sowohl Schweißen als auch Schneiden des Werkstücks ermöglicht.If the compact cell or cobot welding cell is equipped with additional axes (positioning device), the cobot can be taught the position points very quickly by moving them by hand without any programming knowledge and at the same time workpieces can be positioned in the optimal welding position using the additional axes and thus processed productively on multiple sides. The cobot carries out a precise movement of the torch, the welding system delivers the perfect seam. The collaborative robot preferably has a learning mode to learn a working movement of the welding torch to process the workpiece and a working mode to carry out the working movement learned in the learning mode, whereby the working mode enables both welding and cutting of the workpiece.
Ferner ermöglicht die Positionierung des Schweißroboters an den Seitenwänden der Schutzumhausung oder dem Zellendach, dass der Schweißroboter durch Verfahren der Schutzumhausung zur Umschließung eines jeweiligen Arbeitsbereiches ebenso mitverfahren und zur Bearbeitung des in dem Arbeitsbereich liegenden Werkstücks genutzt werden kann. Eine solche Ausführungsform bietet somit nicht nur eine optimale Kompaktheit bzw. Raumnutzung der Kompaktzelle, da durch eine solche Befestigung mehr Arbeitsfläche am zugehörigen Schweißtisch realisiert werden kann, sondern verhindert ebenso etwaige Restriktionen die sich beim Verfahren der Schutzumhausung um oder durch eine festgelegte Schweißroboterposition ergeben würden.Furthermore, the positioning of the welding robot on the side walls of the protective housing or the cell roof enables the welding robot to move along with the protective housing to enclose a respective work area and to be used to process the workpiece located in the work area. Such an embodiment therefore not only offers optimal compactness or space utilization of the compact cell, since such an attachment allows more work surface to be realized on the associated welding table, but also prevents any restrictions that may arise during the process. the protective enclosure around or through a fixed welding robot position.
Bevorzugt ist die Führungsvorrichtung der Schutzumhausung jedoch zumindest so gegenüber der Position des Schweißroboters konfiguriert, dass der Schweißroboter durch die Schutzumhausung in der ersten Position und bevorzugt auch durch die Schutzumhausung in den anderen Positionen von jeder Seite umschließbar ist und vor jedem Schweißvorgang automatisch alle Seiten schließt. Durch solch eine Konstruktion ist es möglich eine optimale Sicherheit für den Schweißer zu gewährleisten ohne die Bewegung der Schutzumhausung zu beeinträchtigen.Preferably, however, the guide device of the protective housing is configured at least in relation to the position of the welding robot in such a way that the welding robot can be enclosed from every side by the protective housing in the first position and preferably also by the protective housing in the other positions and automatically closes all sides before each welding process. Such a construction makes it possible to ensure optimal safety for the welder without impairing the movement of the protective housing.
Neben einer festen Aufnahme des Schweißroboters, durch z.B. Schraubenfixierungen, kann der Schweißroboter bevorzugt auch auf einem Roboterführungssystem, d.h. einer Schiene oder einer exzentrischen Schwenk- bzw. konzentrischen Rundachse auf dem Schweißtisch oder erneut jeweils an der Seitenwand der Schutzumhausung oder am Zellendach positioniert werden. In einer äußerst bevorzugten Ausführungsform kann der Schweißroboter so über ein externes Kontrollsystem selbstständig auch zwischen den oben genannten, modular definierten Teilarbeitsbereichen verfahren oder zwischen den jeweiligen Arbeitsbereichen wechseln, und so selbst komplexe, räumlich verteile Arbeitsschritte bewältigen. Somit können durch die Wahl des Roboterführungssystems die Verfahrensschritte noch weiter optimiert werden und durch die minimale Flächenanforderung (z.B. der Rundachse) zusätzlicher Arbeitsbereich geschaffen werden.In addition to a fixed mounting of the welding robot, e.g. by means of screw fixations, the welding robot can preferably also be positioned on a robot guidance system, i.e. a rail or an eccentric swivel or concentric rotary axis on the welding table or again on the side wall of the protective housing or on the cell roof. In an extremely preferred embodiment, the welding robot can thus independently move between the above-mentioned, modularly defined partial work areas or switch between the respective work areas via an external control system, and thus manage even complex, spatially distributed work steps. The process steps can thus be further optimized by choosing the robot guidance system and additional work area can be created thanks to the minimal area requirement (e.g. of the rotary axis).
Zusammenfassend lässt sich aufgrund der oben genannten Merkmale somit eine kompakte Schweißzelle realisieren, die insbesondere durch die verfahrbare Schutzumhausung und den dadurch entstehenden wechselseitigen Schweißbetrieb nicht nur optimierte Verfahrensschritte bei maximaler Arbeitsflächenausnutzung zulässt, sondern ebenso in jedem Verfahrenszeitpunkt einen bestmöglichen Schutz für den jeweilig anwendenden Schweißer bereitstellt. Dabei fungiert die Schutzhaube, als Kombination aus zumindest einer Seitenwand und einem Dach, vorzugsweise zunächst vorrangig als primäre Schutzvorrichtung der integrierten Elemente, wobei durch in der Innenseite der Schutzumhausung, auf Rolltoraufhängungen gelagerte Rolltorvorrichtungen einen unter der Schutzumhausung liegenden Arbeitsbereich vollständig umschließen und so den Schweißer vor schädlichen Effekten während des Schweißbetriebs abschotten kann. Die Schutzumhausung ist ferner auf einer pneumatisch anfahrbaren Führung an einem Grundrahmen gelagert, sodass sie zwischen einer ersten Position zur Umschließung eines ersten Arbeitsbereiches und zumindest einer zweiten Position zur Umschließung eines zweiten Arbeitsbereiches verfahren werden kann. Durch eine solche Konstruktion kann ein optimales Wechselschweißen, wie oben genannt, verwirklicht werden. Darüber hinaus kann die Führung vorzugsweise so konstruiert sein, dass der in zumindest einen der Arbeitsbereiche positionierte, durch mehrere Freiheitsgrade ansteuerbare Schweißroboter zumindest in einer Position von allen Seiten umschlossen werden kann, was nicht nur einen bestmöglichen Schutz, sondern auch einen für den Roboter größtmöglichen Arbeitsbereich sichert. Weitere Merkmale, wie etwa der modulierbare Schweißtisch, realisieren zudem eine individuell für den jeweiligen Schweißprozess benötigte Anpassungsmöglichkeit, welche durch eine mögliche Einteilung der Arbeitsbereiche in Teilarbeitsbereiche durch eine Kombination aus modulierbaren Rolltorvorrichtungen und Trennwänden weiter maximiert werden kann.In summary, the above-mentioned features make it possible to create a compact welding cell which, in particular thanks to the movable protective housing and the resulting alternating welding operation, not only allows for optimized process steps with maximum use of the work area, but also provides the best possible protection for the welder at any time during the process. The protective hood, as a combination of at least one side wall and a roof, preferably initially functions primarily as the primary protective device for the integrated elements. whereby roller shutter devices mounted on roller shutter suspensions on the inside of the protective housing completely enclose a work area located under the protective housing and can thus shield the welder from harmful effects during welding. The protective housing is also mounted on a pneumatically actuated guide on a base frame so that it can be moved between a first position for enclosing a first work area and at least a second position for enclosing a second work area. Such a construction enables optimal alternating welding, as mentioned above, to be achieved. In addition, the guide can preferably be designed so that the welding robot positioned in at least one of the work areas and controllable by several degrees of freedom can be enclosed from all sides in at least one position, which not only ensures the best possible protection but also the largest possible work area for the robot. Other features, such as the modular welding table, also provide the ability to adapt to the individual welding process required, which can be further maximized by dividing the work areas into sub-work areas using a combination of modular roller shutter devices and partition walls.
Eine solche Kompaktzelle bietet somit eine bestmögliche Individualisierung bei maximaler Kompaktheit und Transportierbarkeit. Zudem kann die Kompaktzelle vorzugsweise eine mobile Kompaktzelle sein, welche zum Transport zumindest eine Gabelstaplertasche umfasst, sodass insbesondere in einer der beiden Positionen der Schutzumhausung die Kompaktzelle durch die Gabelstaplertasche mit einem Hubwagen transportiert werden kann und so einen noch einfacheren Transport der Kompaktzelle ermöglicht. Bevorzugt können auch Räder an der Unterseite der Kompaktzelleverwendet werden.Such a compact cell therefore offers the best possible customization with maximum compactness and transportability. In addition, the compact cell can preferably be a mobile compact cell, which includes at least one forklift pocket for transport, so that in one of the two positions of the protective housing in particular, the compact cell can be transported through the forklift pocket with a pallet truck, thus making transport of the compact cell even easier. Wheels can also preferably be used on the underside of the compact cell.

Ferner ist der oben genannte Grundrahmen 25 bzw. die Führungsvorrichtung 24 in diesem Fall so konfiguriert, dass die Schutzumhausung 3 nacheinander von einer ersten Position zur Umschließung des ersten Arbeitsbereiches A1 über eine zweite Position zur Umschließung des zweiten Arbeitsbereiches A2 bis zumindest zu einer einer dritten Position zur Umschließung des dritten Arbeitsbereiches A3 und zurück verfahrbar ist, sodass durch die Bewegung der Schutzumhausung 3 zumindest jeder Bereich des unter der Schutzumhausung 3 liegenden Schweißtisches 8 einmal umschlossen werden kann und gerade nicht umschlossene Bereiche frei liegen. Dies hat den Vorteil, dass eine beliebige Anzahl an Arbeitsbereichen zur Verfügung stellen kann und somit nicht nur ein bzw. zwei Schweißarbeiter zusätzlich parallel zum Schweißroboter Werkstücke 11, 13, 17 vorbereiten bzw. bearbeiten können, sondern die Kompaktzelle Z je nach Anforderung des jeweiligen Schweißauftrags beliebig zusammengesetzt werden kann.
